The 1AZ FSE will drop right in an Allion. You are upgrading from 1.8L - 130HP to a 2.0L - 148 HP engine that as long as your Allion is 2001 to 2008 will be fine. It is OEM in Camry and Rav4. Just get everything, I mean everything, from donor car. ECU, EVAP system, wiring harnesses, and you are good

It's a 'square' engine, 89mm bore and 89mm stroke. That relatively short stroke improves HP, but at just a slight loss of low-end torque. But It's a good engine. It's a much bigger piston than the 1.8L. And a shorter stroke, producing more HP at the cost of low-end torque. But it's not a cargo=hauler, trailer-puller (within limits) so that is really not a concern. The shorter stroke also gives it a slower piston speed, allowing a higher red-line rpm

Just make sure you don't get an 1 AZ FBE. That is an alcohol burning engine. Not even flex fuel, runs on strictly E85

Meaning the best is 1az fee, right?

1az fse?

No, I don't mean to say the 1AZ FE or FSE is better. That and the 1ZZ series are both superior engines. The 1AZ is just a bit bigger bore, a bit more powerful but not really better. It does not get the economy of a 1ZZ, but has more HP. If I had to choose, I would go with the 1.8 1ZZ FE. But no dissing the 1AZ
